[seqfan] Numbers not of form x^3 + 2y^3 + 3z^3

[Peter Munn]

x, y, z are integers.

A014136 had conflicting indications as to whether {36, 288} was known to
be the complete set, and some of us have provisionally resolved this in
favour our own lack of knowledge.

Does anyone know whether it remains an open problem? And/or have
references that could be added to A014136?

Best regards,

Peter
