Corneth, Aug 03 2020: (Start) 251633402 is in the sequence as 251633402 = 1^10 + 2^10 + 2^10 + 2^10 + 5^10 + 6^10 + 6^10 + 6^10 + 6^10. 383052503 is in the sequence as 383052503 = 1^10 + 1^10 + 4^10 + 5^10 + 5^10 + 5^10 + 5^10 + 6^10 + 7^10. 626642399 is in the sequence as 626642399 = 1^10 + 1^10 + 3^10 + 3^10 + 3^10 + 4^10 + 6^10 + 7^10 + 7^10.
