There is a summary at the end of this file. When sending new sequences, start numbering them A000001, A000002, A000003, etc. Use 6-digit numbers. I will renumber them. If you are planning to send many sequences, I can issue you a block of A-numbers and you can number them yourself.
U lines give the beginning of the sequence.
If possible, give enough terms to fill 3 lines on the screen. The numbers should be separated by commas, with no spaces or tabs. Don't give more than 3 lines. At least 4 terms are required. The terms must be integers.
