Pollock's conjectures
Pollock's conjectures are two closely related unproven conjectures in additive number theory. They were first stated in 1850 by Sir Frederick Pollock, better known as a lawyer and politician, but also a contributor of papers on mathematics to the Royal Society. These conjectures are a possible extension of the Fermat polygonal number theorem to three-dimensional figurate numbers, also called polyhedral numbers.
*Pollock tetrahedral numbers conjecture: Every positive integer is the sum of at most five tetrahedral numbers.
*Pollock octahedral numbers conjecture: Every positive integer is the sum of at most seven octahedral numbers.
