100099

Appears in sequences

• Number of positive integers <= 2^n of form x^2 + 16*y^2.at n=20A000018
• Suppose you take the ten digits 0..9, arrange them in any order and then either concatenate adjacent ones or separate them with a plus or minus sign, e.g., 98-76+5-4-32+10 or 9-8-765+3041-2. The first expression totals to "1", the second example totals to "2275". This sequence lists the positive integers that cannot be expressed in this way.at n=22A108224
• Numbers k such that k and k^2 use only the digits 0, 1, 4, 8 and 9.at n=54A136867
• Numbers k such that k and k^2 use only the digits 0, 1, 5, 8 and 9.at n=38A136874
• Numbers k such that k and k^2 use only the digits 0, 1, 6, 8 and 9.at n=40A136879
• Numbers k such that k and k^2 use only the digits 0, 1, 7, 8 and 9.at n=40A136880
• Numbers k such that k and k^2 use only the digits 0, 1, 8 and 9.at n=38A136881
• Integers whose decimal representation consists of three distinct digits, one appearing once, one appearing twice, and one appearing three times.at n=23A182040
• 2^(2p-2) modulo p^3 for p=odd primes.at n=17A216160
• (-1)^((p-1)/2)*Binomial(p-1,(p-1)/2) mod p^3 where p is the n-th prime.at n=17A224807
• Numbers <= 10^6 with valid Luhn mod 10 check digit, sorted lexicographically.at n=11A249854
