A098227

Number of primes with exactly n decimal digits which have repeated digits.

0, 1, 46, 551, 5834, 58667, 552131, 5006366, 44940852, 404204977, 3663002302, 33489857205, 308457624821, 2858876213963, 26639628671867, 249393770611256, 2344318816620308, 22116397130086627, 209317712988603747 (list; graph; refs; listen; history; text; internal format)

	OFFSET	`1,3`
	COMMENTS	`Above n=9 a[n]=A006879[n] because above 10 repetition must occur. At n=10 the sum of digits 0+1+2+3+4+5+6+7+8+9=45 is divisible by 3, so no primes with 10 distinct decimal digits exists, all primes must have repeated digits.`

	EXAMPLE	`Above n=9 a[n]=A006879[n] because above 10 there must be a repetition. At n=10 the sum of digits 0+1+2+3+4+5+6+7+8+9=45 is divisible by 3, so no primes with 10 distinct decimal digits exist.`
