 A145532 Number of numbers removed in each step of Eratosthenes' sieve for 5! 24
 59, 19, 7, 4 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS Number of steps in Eratosthenes' sieve for n! is A133228(n). Number of primes less than 5! is equal = 120-59-19-7-4-1 = 30 = A003604(5). LINKS EXAMPLE a(1)=59 because in first step we removed all numbers divisible by 2 (=60) with exception first one number 2. a(2)=19 because number of numbers divisible by 3 and not divisible by 2 is 20 and we remove all with exception first one number 3.
