Is the Kanji an error? Does EDICT have the listing wrong?

Rikaichan (Which lists EDICT stuff right?) lists it at Nelson 1401, but Nelson 1401 is actually 屢, which EDICT does not list as being in Nelson?

屢 and 屡 are variants (so are 数 & 數, 楼 & 樓 and 薮 & 藪). 屢 is outside the JIS 1 & 2 sets, so may not be listed in some places.

As always thank you. It's strange thought that EDICT lists the one that is in Heisig as being the one in Nelson and not the other way around.

I take it that the other of the variant pairs are not in Nelson, or is it just this one that is missing?

I don't have a copy of Nelson, so can't check for certain. According to KANJIDIC the other pairs are all in Nelson or New Nelson.
