There are (42*41*40*39*38*37)/(6*5*4*3*2*1) = 5 245 786 combinations.
Assuming that repeated numbers are allowed, the number of possible combinations is given by 40 * 40 * 40 = 64000.If repeated numbers are not allowed, the number of possible combinations is given by 40 * 39 * 38 = 59280.
(43*42*41*40*39)/(5*4*3*2*1) = 962598
