Bounds on the Minimum Distance of Linear Codes
Fill in q, n, k, and get bounds on the maximal minimum distance of the linear codes over GF(q) with length n and dimension k.

Classifying Subspaces of Hamming Spaces
By P. R. J. Östergård. The following codes with minimum distance greater than or equal to 3 are classified: binary codes up to length 14, ternary codes up to length 11, and quaternary codes up to length 10.
Constant Weight Binary Codes
Lower bounds (and in some cases exact values) for A(n,d,w), the size of the largest binary code of length n, distance d and constant weight w.
Covering Codes
The best known bounds on the size of binary covering codes of length up to 33 and covering radius up to 10. Compiled by Simon Litsyn.
