## Abstract A new lower bound on the number of nonβisomorphic Hadamard symmetric designs of even order is proved. The new bound improves the bound on the number of Hadamard designs of order 2__n__ given in [12] by a factor of 8__n__βββ1 for every odd __n__β>β1, and for every even __n__ such that 4_
## Abstract It is wellβknown that the number of designs with the parameters of a classical design having as blocks the hyperplanes in __PG__(__n, q__) or __AG__(__n, q__), __n__β₯3, grows exponentially. This result was extended recently [D. Jungnickel, V. D. Tonchev, Des Codes Cryptogr, published on
