What is recorded here?
Found 27^5 + 84^5 + 110^5 + 133^5 = 144^5 by computer search, disproving Euler’s proposed lower bound on the number of like powers needed to sum to another.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The displayed identity is a finite exact witness. The historical search used a CDC 6600; it is not evidence of a modern AI-model contribution. The source’s minimality statement requires its search scope and is not established merely by checking the equality.
