The best one we found was for THREE, which 4-shifts to XLVII, which Anil punctuated without rearrangement to either (X/L)(V)+I+I or X/(L/V)+I+I, both of which = III.
Here are some other self-referential results: (number of shifts in parentheses)
ONE (13) = bar & NONE (13) = a-bar, its infinitely perfect opposite, (one/none = [infinity])
NONE (10) = xyxo > X/Yx0 = 0 = none, (a common cheat calling 0 O, as in reciting phone nrs.)
TEN (10) = dox > "Do X."--a recipe for generating ten. (by a ten shift)
FIRST (9) = orabc > or ABC--first principles.
TENTH (10) = doxdr > "Do X, Dr."--a "professorial" extension of the ten ten-shift above.
NTH? (11) = Yes! (an inside joke for whoever knows what is nth)
No Arabic number word shifts to a five-letter Web3 word, and only two shift to four-letter words:
NONE (4) = divs (demons); NINE (13) = Avar (a people and language). As well,
FIVE (19) = y box (a Web3 electricity phrase) and SEVEN (10) = co-fox, a possible nonce word.
Far more Roman than Arabic numbers gave words, but only three yielded (forced) cognates:
XII (3) = all > a L=L--ie, all L's are the same and = 12 alphanumerically. (groan) Or all > al. L--an other way of saying XII. (Therefore 12 = 50?--a $38 mark-up!)
CI (21) = XD. Doubling it > (X)(D)(X/D) = C/I, a punc lib charade of CI. (10x500x1/50=100/1)
XXI (15) = MMX. Although 21 [not equal to] 2010, they have the same digit sum, 3. 2010 also resembles 21 and becomes 21 if the zeroes are removed, being mere nothings. Similarly, XXII = MMXX (22=2020) and XXIII = MMXXX (23=2030).
Of the many non-cognate words from Romans, these four-letter W3 words were found:
XLII (22) = Thee! (Thee art 42, the meaning of life, the universe & everything, because ...)
XVII (22) = Tree (the root of it all).
LXXI, CXXI, DXXI (7) = seep, jeep, keep.
MXXI + XX (7) = teepee, (a teepee-made-for-two Romans)
LMXXI (7) = steep--although 971 is more properly CMLXXI.
XCVI (22) = tyre. This is the only Roman example without double letters, four different letters, one for each corner of the vehicle.
CXII, DXII, MXII (3) = fall, gall, pall.
DCCX (1) = eddy.
MDCC (23)= jazz.
Again, no legitimate single number gave a five letter word or longer.
Allowing letter rearrangement after a shift gave some longer words, selfies and other fun results.
ZERO (9) = inax> a nix (a zero).
THREE (10) = drboo> Dr. Boo brood; (7) = aoyll> alloy; (22) = pdnaa> panda, (three fivers)
FOUR (12) = ragd> Drag darg, Gard grad.--four anagrams in a polyanagram sentence. (Gard is a place in France but not in Web3, where it wouldn't fit.)
FIVE (13) = svir> V. sir. (Five, Mister.)
EIGHT (22) = aecdp> caped paced. (Superman?)
EIGHT (7)-lpnoa> plano.
NINE (10) = xsxo > (X-X0)'s = nine's: (10-1)'s.
TWELVE (4) = xaipzi> XII--zap! (Twelve--take that!)
TWELVE (22) = psahra> A-sharp harpas (off-key molluscs).
FORTY (18) = xgjlq> XL gjq. (Forty gjq might be dangerous if only we knew what a gjq was!)
FIFTY-FIVE (9) = orochoren> re Orochon (a people, W3; or Orochi). Is one called an Orochoner? If so this is by far the largest single word shiftgram-anagram result found for any number word, possibly for any w'ord (?). And it's a 9-shift of a nine letter word.
HUNDRED (11) = sfyocpo> posy of C (a hundred flowers).
THREE THOUSAND lzjuu lzGMKsfy: while no anagram is possible this one is notable for having G. M and K together, the three different one letter equivalents of thousand: Grand ($), Roman M and Kilo-, totaling three thousand. (3000 metric Roman dollars?)
FIRST (21) = admno> monad (= one).
SECOND (16) = iusedt> Used, it. (second hand).
FOURTH (14) = tcifhv> cf. IVth (see fourth).
FIFTH (19) = ybyma> By May! (Pay by the fifth month or else!) (For a fifth of whiskey?)
SIXTH (11) = dties> Ed set diets, sited ID-set edit's tides, (six anagram sentence)
SEVENTH (19) = lxoxgma. Doubling > Go! Am LXX/X, log max. (LXX/X=seven.) Anil couldn't resist cheating here by zipping two numbers together in a polyanagram.
TENTH (11) = epyes> Spy E+E. (Letters five + five = ten. But no, that's upside down. It's two tenths make a fifth! Yet two fives make a ten. Isn't life strange.)
TENTH (4) = xirxl, a near miss: xirxl, by replacing r with m, rearranges to MLXXI, which 22-shifts to ihtte > tithe (a tenth). Tithe also trans-substitutes to tenth by replacing i with n.
MDCLXVI (18) = evudpna> unpaved dupe van. (Pun, Dave!)-- pun on 666, rough road/ride to hell.
For good measure, we throw in three apt non-number shiftgrams. The first two are direct hits, no rearrangements. The third use a half reversal for a > < implosion structure.
DOXY (3+23+6) = Grab a luv, Jude, (loose woman)
USA (12) = Gem. (Columbia, the Gem of the Ocean)
Eckler (16) = usabuh> USA hub! (logology hub)
Iowa City, IA
