OEIS Sequences

Array read by antidiagonals: see A128195 for details. A126062

Number of integers <= 2ⁿ of form 4 x² + 4·y + 5 y². A76

Positive numbers k such that k and 5·k are anagrams in base 6 (written in base 6). A23067

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
