Examples

			3 ("11" in binary, A007088) is present as the length of that only run of 1's is 2, and 2 > 1+0, where 0 is the total number of 0's to the right of that run.
60 ("111100" in binary) is present as 4 > 2+1.
246 ("11110110" in binary) is present as the length of the leftmost run of 1-bits is 4, and 4 > 1+2, where 2 is the total number of 0's located anywhere to the right of that run.
