Examples

“Twice a triangular number⟳ is a heteromecic number⟳.”

“[1] Again, then, to take⟳ a fresh start⟳, a number⟳ is called heteromecic if its representation, when graphically described in a plane, is quadrilateral and quadrangular, to be sure, but the sides are not equal to one another, nor is the length equal to the breadth, but they differ⟳ by 1. Examples are 2, 6, 12, 20, 30, 42, and so on, for if one represents them graphically he will always construct them thus: 1 times 2 equals 2, 2 times 3 equals 6, 3 times 4 equals 12, and the succeeding ones similarly, 4 times 5, 5 times 6, 6 times 7, 7 times 8, and thus indefinitely, provided only that one side is greater than the other by 1 and by no other number⟳.”
