COMMENTS
Any multiple of a term is again a term of this sequence. See A063923 for the primitive solutions. See A007666 for similar solutions for other powers. - M. F. Hasler, Nov 17 2015
Nontrivial means at least two of a,b,c,d,e are nonzero. - Jianing Song, Jan 24 2020
EXAMPLE
72^5 = 19^5 + 43^5 + 46^5 + 47^5 + 67^5;
94^5 = 21^5 + 23^5 + 37^5 + 79^5 + 84^5;
107^5 = 7^5 + 43^5 + 57^5 + 80^5 + 100^5.
