I'm not sure that I can buy the argument that these to timesheets can have the same traces. There have to be material differences otherwise either or both of you would gte paid twice, or some random other(s) would be collecting your wages.

Ok... lets allow that the wa-representations and indeed the traces of the timesheets carry no distinguishing marks that allow and observer to discriminate - I such a situation I think that you have only one resource that happens to have many names.

:-)... well not for me... I don't know what a "Mersenne prime" is let alone the 46th one, though that seem to clearly be descriptive of some ordinal position in a series. (/me heads for wikipedia).

Your message did describe a number (at least I prepared to accept that it did). It did tell me that it was prime (or at least AFAICT contained symbols with that intent), though I have to rely on background knowledge to understand the concept of primeness.
