✦ Synopsis


We describe three applications of Magma to problems in the area of designs and the associated codes:

• Steiner systems, Hadamard designs and symmetric designs arising from an oval in an even-order plane, leading in the classical case to bent functions and difference-set designs; • the Hermitian unital as a 2-(q 3 + 1, q + 1, 1) design, and the code over Fp where p divides q + 1; • a basis of minimum-weight vectors for the code over Fp of the design of points and hyperplanes of the affine geometry AG d (Fp), where p is a prime.
