N2 - In this paper, codes over double-struct F sign5 with parameters [36,18,12], [48, 24, 15], [60, 30, 18], [64, 32, 18] and [76, 38, 21] which improve the previously known bounds on the minimum weight for linear codes over double-struct F sign5 are constructed from conference matrices. Through shortening and truncating, the above codes give numerous new codes over double-struct F sign5 which improve the previously known bounds on minimum weights.
