用maple解方程2ab+2bc+2cd+2de-e^2=-5780613042962ac+2bd+2ce-2de-a^2=-1998272010782-2ab+2ad+2be-2ce-d^2=-1194036100249-2ac+2ae-2be-2cd-b^2=-10335362254832ad+2ae+2bc+2bd+c^2=3075230855865好像有整数解
用maple解方程
2ab+2bc+2cd+2de-e^2=-578061304296
2ac+2bd+2ce-2de-a^2=-1998272010782
-2ab+2ad+2be-2ce-d^2=-1194036100249
-2ac+2ae-2be-2cd-b^2=-1033536225483
2ad+2ae+2bc+2bd+c^2=3075230855865
好像有整数解
