Table of n, a(n) for n=0..66.

Example

a(11) = 17 because 11 in base 5 is 21, its complement in base 5 is 23 and the digit reverse is 32 that is 17 in base 10.

Maple

P:=proc(q, h) local a, b, k, n; print(h-1); for n from 1 to q do a:=convert(n, base, h); b:=0;
for k from 1 to nops(a) do a[k]:=h-1-a[k]; b:=h*b+a[k]; od; print(b); od; end: P(10^2, 5);
