23 is the number of interconnectedness, in that any given number can be related to it with relative ease. For example, take another traditional "power number", 666. 6+6+6 = 18, 1+8 = 9, 9 = 3^2^, an inverse 23. A randomly chosen number, 8458: 8+4+5+8 = 25, 25 = 5^2^ (a nice self-inversion on its own), 2+3 = 5, the natural companion to 23 and also relates to the pentagon, pentagram, pentathlon, pentasaurus and others. (666 can also be related in that 6 = 2x3, another natural companion, so 666 is a 23 tripled)
2^3^ is eight

Table numbers in restaurants, room numbers in hotels, prices on your receipts, answers in your maths class, rates on your mortgage, it will occur somewhere. It follows those who know about it.
