In additive number theory, Pollock's conjectures are unproven^[1] conjectures that every positive integer is the sum of at most five tetrahedral numbers^[2], and that every positive integer is the sum of at most seven octahedral numbers.^[3] They were first stated in 1850 by Sir Frederick Pollock^[3], better known as a lawyer and politician but also a contributor of papers on mathematics to the Royal Society. These conjectures are partial generalization of Fermat's polygonal number theorem to three dimensional figurate numbers, also called polyhedral numbers.
