EXAMPLE

13 in base 8 is 15: moving the most significant digit as the least significant one we have 51 that is 41 in base 10.

MAPLE

with(numtheory): P:=proc(q, h) local a, b, k, n; print(0);

for n from 1 to q do

a:=convert(n, base, h); b:=[]; for k from 1 to nops(a)-1 do b:=[op(b), a[k]]; od; a:=[a[nops(a)], op(b)];

a:=convert(a, base, h, 10); b:=0; for k from nops(a) by -1 to 1 do b:=10*b+a[k]; od;

print(b); od; end: P(10^4, 8);

MATHEMATICA

roll[n_, b_] := Block[{w = IntegerDigits[n, b]}, Append[Rest@ w, First@ w]]; b = 8; FromDigits[#, b] & /@ (roll[#, b] & /@ Range[0, 69]) (* Michael De Vlieger, Mar 04 2015 *)
