Alexis Claude Lemaire (born 1980) is a French mathematician and art student at the University of Reims. He is the world champion in computing the 13th-degree root of randomly generated 100- and 200-digit numbers. On May 10, 2002, he calculated the 13th degree element from a randomly generated 100-digit number in 13.33 seconds, beating the then-record set by Willem Klein (88.8 seconds). On December 17, 2004, Lemaire broke his record by 3.625 seconds. He found the root of the 100 digit numbers of 3,893,458,979,352,680,277,349,663,255,651,930,553,265,700,608,215,449,817,188, 566,054,427,172,046,103,952,232,604,799,107,453,543,533, amounting to 45,792,573. On April 6, 2005, he managed to calculate the root of step 13 from the 200 digit in 8 minutes and 33 seconds. November 2007 reduced the time to 72.4 seconds. Eventually, on December 10, 2007, he managed to calculate the element in 70.4 seconds. The result was 2,407,899,893,032,210.
