```David Seal posted the following "sporadic solutions" for reverse-sum
iterations in the Usenet Newsgroup rec.puzzles in January of 1996:

"Base 4:
1033202000232(n 2s)2302333113230
After 6 iterations, becomes same thing with n increased by 3.
Base 11:
1246277(n As)A170352495681825A5026571A506181864A5143171(n 0s)0872542
After 6 iterations, becomes same thing with n increased by 1.
Base 17:
10023AB83E3B983CFGEC556G4G010(n 0s)0FGCG10FG505GF020CGF(n Gs)GG11G4F655D
DGGB299B3D38BB320G
After 6 iterations, becomes same thing with n increased by 1.
Base 20:
There is a >200 digit number of the same general form which grows
indefinitely without ever producing a palindrome, but I'm not going
to try to transcribe it here!
Base 26:
1N5ELA6C(n Ps)P6E7(n 0s)0D59ME5N
After 4 iterations, becomes same thing with n increased by 1."

Here are representative cycles corresponding to each of these solutions:
