FORMULA
a(n) = reverse(6 * a(n-1)) where a(1) = 1.
EXAMPLE
a(4) = reverse(6 * a(3)) = reverse(6 * reverse(6 * a(2))) = reverse(6 * reverse( 6 * reverse(6 * a(1)))) = reverse(6 * reverse(6 * reverse(6))) = reverse(6 * 63) = 873.
PROG
(Magma) f:=func<n|Seqint(Reverse(Intseq(6*n)))>; a:=[1]; for n in [2..25] do Append(~a, f(a[n-1])); end for; a; // Marius A. Burtea, Jan 03 2020
