23 (number) (Wikipedia)

Wikipedia's article on the number 23, consulted in 2026, is a community edited reference page rather than a peer reviewed publication. It is reliable for the standard mathematical classification cited here, that 23 is the fifth Sophie Germain prime and the second term of the Cunningham chain of the first kind running two, five, eleven, twenty-three, forty-seven, and for basic factual claims of that kind. Use it for that narrow mathematical purpose; a claim about 23's place in numerological or conspiracy theory traditions needs a dedicated source on that specific claim.
