Like here is one:
(462 + 482 + 722)(1722 + 2582 + 4302 + 6022 + 17622) =
6152 + 30752 + 141452 + 159902 + 1884972 = 21074114
Just like to stare at it for some reason.
Seem to like sums of lots of squares. Continuing, like here are two more sums of 5 squares to a square:
42 + 62 + 102 + 142 + 862 = 882
and
862 + 1292 + 2152 + 3012 + 8812 = 9682
And here went ahead and summed 7 to get a square:
349672 + 7522 + 11282 + 18802 + 26322 + 41362 + 48882 = 357212
An example from even earlier though, where rely on previous known result is here where was talking size of what I now call the unary form of the two conics equation:
60*2551100302 + 2551100292 = 19924730292
That is related to something, talk it here and for reference: 297182 - 61*38052 = -1
Liking that the easier solution, which is historically known so know from other sources and didn't figure it out myself, fits nicely there.
Putting in one place is useful to me for staring at them purposes.
