COMMENTS
Whether these numbers are actually nonessential is not proved. I merely have numerical evidence at this point.
EXAMPLE
Any number is the sum of three triangular numbers (Gauss). The 8th triangular number (36) seems nonessential for these sums. After eliminating 8, the eleventh triangular number seems to be nonessential.
