The On-Line Encyclopedia of Integer Sequences
N. J. A. Sloane
This article gives a brief introduction to the On-Line Encyclopedia of Integer Sequences (or OEIS). The OEIS is a database of nearly 90,000 sequences of integers, arranged lexicogr…
Modular and p-adic cyclic codes
A. R. Calderbank, N. J. A. Sloane
This paper presents some basic theorems giving the structure of cyclic codes of length n over the ring of integers modulo p^a and over the p-adic numbers, where p is a prime not di…
Complete Weight Enumerators of Generalized Doubly-Even Self-Dual Codes
Gabriele Nebe, H. -G. Quebbemann, E. M. Rains +1
For any q which is a power of 2 we describe a finite subgroup of the group of invertible complex q by q matrices under which the complete weight enumerators of generalized doubly-e…
Approximate Squaring
J. C. Lagarias, N. J. A. Sloane
We study the ``approximate squaring'' map f(x) := x ceiling(x) and its behavior when iterated. We conjecture that if f is repeatedly applied to a rational number r = l/d > 1 then e…
Numerical Analogues of Aronson's Sequence
Benoit Cloitre, N. J. A. Sloane, Matthew J. Vandermast
Aronson's sequence 1, 4, 11, 16, ... is defined by the English sentence ``t is the first, fourth, eleventh, sixteenth, ... letter of this sentence.'' This paper introduces some num…
