The decimal expansion of this palindromic prime contains 8527 instances of Nelson Mandela's prison number, 46664. This number of instances is less than the number of days that elapsed between his sentence of life imprisonment, on 12 June 1964, and his release from jail, on 11 February 1990. In October 2003, he said "46664 was my prison number. For over 18 years I was imprisoned on Robben Island, known just as a number. Millions of people today infected with AIDS are just that - a number. They too are serving a prison sentence - for life."

Verification data:

The Top 5000 Primes is a list for proven primes only. In order to maintain the integrity of this list, we seek to verify the primality of all submissions.  We are currently unable to check all proofs (ECPP, KP, ...), but we will at least trial divide and PRP check every entry before it is included in the list.
