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.
The following performances have not yet been verified :
G. Uday Shankar, 7,000 digits
The first 10,000 digits of Pi
are divided into 2,000 5-digit blocks. The testers call out one of these 5-digit
sequences, and the candidate must reply with the 5-digit numbers on either side of the number chosen. This happens 50 times.
