OEIS Sequences

Integers whose decimal representation consists of three distinct digits, one appearing once, one appearing twice, and one appearing three times. A182040

Numbers such that the digital sums in bases 2, 3, 5 and 10 all are equal. A135128

a(n) = ∑_k=0..n (-1)^A010060(n-k)*[(n+1) mod (k+1) = 0]*10^k, where [] denotes the Iverson bracket. A101564

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. A108224
