Appears in sequences

• Base 5 digits are, in order, the first n terms of the periodic sequence with initial period 3,1.at n=7A037584
• Numbers k > 1 such that, in base 9, k and k^2 contain the same digits in the same proportion.at n=5A061663
• Numbers n which when converted to base 5, reversed and converted back to base 10 yield a number m such that n mod m = 0. Cases which are trivial or result in digit loss are excluded.at n=20A091079
• a(n) = 5*a(n-1) + a(n-2) - 5*a(n-3), for n>4, with a(1)=1, a(2)=0, a(3)=4, a(4)=16.at n=9A123010
