`Equal Sums of Like Powers`

Non-negative Integer Solutions of

a₁^k + a₂^k + a₃^k + a₄^k+ a₅^k + a₆^k + a₇^k + a₈^k + a₉^k+ a₁₀^k

= b₁^k + b₂^k + b₃^k + b₄^k + b₅^k + b₆^k + b₇^k + b₈^k+ b₉^k+ b₁₀^k

( k = 1, 2, 3, 4, 5, 6, 7, 8, 9 )

Solution of this type was first found by A.Letac in 1940's.[5] [25]

[ 0, 3083, 3301, 11893, 23314, 24186, 35607, 44199, 44417, 47500 ] = [ 12, 2865, 3519, 11869, 23738, 23762, 35631, 43981, 44635, 47488 ]

This second solution was obtained by G.Palama in 1950[33] and C.J.Smyth in 1990.[22] Their methods both were based on Letac's method. See also ( h = 1, 2, 4, 6, 8 ) for more information.
The smallest two solutions are found by Peter Borwein, Petr Lisonek and Colin Percival in 2000. See http://Euler.free.fr/oldresults.htm .

[ 0, 12, 125, 213, 214, 412, 413, 501, 614, 626 ] = [ 5, 6, 133, 182, 242, 384, 444, 493, 620, 621 ]
[ 0, 63, 149, 326, 412, 618, 704, 881, 967, 1030 ] = [ 7, 44, 184, 270, 497, 533, 760, 846, 986, 1023 ]
