%N Positive integers that cannot be written as a sum of a practical number and a 12-gonal number.
%C Somu and Tran (2024) proved that there are infinitely many such integers. More generally, infinitely many positive integers cannot be written as a sum of a practical number and an s-gonal number if s is a multiple of 12.
