[math-fun] AnAgraM + aNAGram = AnagRAm
Hello Math-Fun (Gilles E.-F. and Alexandre W. in BC copy), Let a + b = c and a < b < c and a, b, c = anagrams of each other. What is the smallest possible "a" with this property? Have all a's under one million been computed already? Two examples: a = 41904 b = 49140 c = 91044 and a = 164907 b = 604197 c = 769104 Sorry of this is old hat. Best, É.
EA: "Let a + b = c and a < b < c and a, b, c = anagrams of each other. What is the smallest possible 'a' with this property?" 459 I think possibly this is how OEIS A160851 might start (but it doesn't). In fact, that sequence appears to be missing either the a or the b complement for each of its included terms.
Many thanks, Hans! Best, É.

If you consider a version that allows leading zeros, you can also have 045 + 405 = 450! --Neil Bickford On Sun, Jan 12, 2020 at 2:49 PM Éric Angelini <bk263401@skynet.be> wrote:

EA: "Have all a's under one million been computed already?" It seems that all c's under one million have: http://oeis.org/A203024/b203024.txt However, this list might include (I'm not sure) instances where a=b (you asked for a<b).
Indeed, well found, bravo Hans! Best É.
