PI MATRIX RECORDS
Rules :
Each line of PI is numbered and there are 50 digits on each line in blocks of five. The candidate is given a number of a line of PI and then has to either recite the line forward or backwards. Or he will be asked to name a certain digit on that line. He also may have to multiply two certain digits on different lines. The candidate has to answer 50 tests and get them all correct.
On 09 October 1999, Creighton Carvello of England was able to pass all these tests on the first 10,050 digits of PI. His attempt took place at the Royal Holloway, University of London, Egham, Surrey, England. Two official witnesses were present.
