For n = 2 through 9, this is the decimal number with n^2 digits all equal to n, then written in base n. For n>9 the reader has to separate the "digits" himself (so this is a fairly unsatisfactory sequence).

This is to A191244 as n^2 is to n.

			For n=3: form the number with 3^2 = 9 digits all equal to 3, 333333333. This is then converted into base 3, to get 212020020002101000.

Cf. A191244.

f:=n->n*(10^(n^2)-1)/9;
g:=n->convert(f(n),base,n);
for n from 2 to 20 do
t1:=g(n);
t2:=nops(t1);
lprint( [seq(t1[t2+1-i],i=1..t2)]);
