 OFFSET 1,1 COMMENTS As the order of addition doesn't matter we can assume terms are in nondecreasing order. - David A. Corneth, Aug 01 2020 LINKS David A. Corneth, Table of n, a(n) for n = 1..10000 (first 1000 terms from T. D. Noe) Samuel S. Wagstaff, Jr., Equal Sums of Two Distinct Like Powers, J. Int. Seq., Vol. 25 (2022), Article 22.3.1. EXAMPLE From David A. Corneth, Aug 01 2020: (Start) 10069120217 is in the sequence as 10069120217 = 29^6 + 46^6. 139314070233 is in the sequence as 139314070233 = 3^6 + 72^6. 404680615040 is in the sequence as 404680615040 = 22^6 + 86^6.
