Comments

A number n is a lunar pseudoprime if it has no lunar divisors with length in the range 2, 3, ..., len(n)-1.

So the present sequence consists of the numbers which do have a lunar divisor of length in the range 2, 3, ..., len(n)-1.

Computed using David Applegate's programs.

Examples

			100 = 10*10.
