There's something funny.
I tried to get the term after :
> 9293949596979899
It should be:
8 0 __ 1 10 2 10 3 10 4 10 5 10 6 10 7 11 8 10 9
(eight(?) zero's, ??? "1"s, ten "2"s, ten "3"s,... )
are we stuck ?
at present I see 10 "1"s, without their count. so it will be between
>=10 (and <20), thus at least 11.
But if we put 11, then we have 12 "1"s
if we put something >11, then we have 11 "1"s...
oh no, wait... if we put 12, then we have 11 "2"s, so there's one "1"
more... does this work ?
7 0 12 1 11 2 10 3 10 4 10 5 10 6 11 7 10 8 10 9
It seems ok ! ??
But like a miracle... it could well not have worked.
Then what? is is always possible to make a modification to get a
consistent term ?
how to choose it , if the "natural" way does not work ?
Or should the sequence then be considered finite ?
