Abstract
We say a natural number~ is abundant if , where denotes the sum of the divisors of~. The aliquot parts of~ are those divisors less than~, and we say that an abundant number~ is pseudoperfect if there is some subset of the aliquot parts of~ which sum to~. We say~ is weird if~ is abundant but not pseudoperfect. We call a weird number~ primitive if none of its aliquot parts are weird. We find all primitive weird numbers of the form ( being odd primes) for . We also find primitive weird numbers of the same form, larger than any previously published.
