[sxfusefo] Small expressions involving e pi phi

Form some constants using the following operations:
+ * - / ^ log root sqrt sqr
On the following base constants:
e pi phi 2pi phi^-1
It should be easy to enumerate all small expressions.

Inspired by a nerdy clock which had pi-o'clock marked between 3 and 4.  We'd only be interested in constants between 1 and 13.

The interval between e and pi o'clock is 25 minutes 23 and 55/60 seconds.
