Comments

These are a subset of the terms of A071774 multiplied by 10, where A071774 are numbers m such that Fibonacci numbers mod m = 2*(m+1). All A071774 terms multiplied by 10 have Pisano periods 3*(n+10) or (n+10). This sequence is the (n+10) subset.

Examples

			The Pisano period of the Fibonacci numbers mod 170 = 180, which is 170+10.
The Pisano period of the Fibonacci numbers mod 1670 = 1680, which is 1670+10.
