Pancake number
represents the maximal number of pieces in which a pancake (or a circle) can be divided into by
linear cuts. They are the bidimensional version of
cake numbers.
In general,
Pancake numbers are often called lazy caterer numbers, or,
more formally, central polygonal numbers.
The first pancake numbers are
1, 2, 4, 7, 11, 16, 22, 29, 37, 46, 56, 67, 79, 92, 106, 121, 137, 154, 172, 191, 211, 232, 254, 277, 301, 326 more terms
