Aoxcmyst

Alexis has been putting together a weird sequence of letters: AOXCMYST. I am puzzled as to what it could mean. The last time she was fixated on writing this sequence: 590N63808. We figured out that it was SPONGEBOB written with numbers.

Hopefully we will be able to figure out this new “code” sequence. It’s kinda neat when she does this. We can often go for months before we figure out what they mean, then when we do figure it out she will come up with another sequence for us. It’s almost like a game.

Any ideas what it could be please reply:
