Comments

Look-and-repeat sequence A225329 with seed 2.

Contains 1, 2, 3 and 5, but not 4.

All terms end with 2 (the seed) and, starting at the fourth, with 3331112, which makes the 5 appear.

All terms except the second begin with 2 or 3; this is a direct consequence of the look-and-repeat rule.

Examples

			The term after 112 is obtained by saying (repeating) two two 1, one one 2, which gives 221112.
