Four methods for constructing anti-Pasch Steiner triple systems are develop
ed. The first generalises a construction of Stinson and Wei to obtain a gen
eral singular direct product construction. The second generalises the Bose
construction. The third employs a construction due to Lu. The fourth employ
s Wilson-type inflation techniques using Latin squares having no subsquares
of order 2. As a consequence of these constructions we are able to produce
anti-Pasch systems of order v for v = 1 or 7 (mod 18), for v = 49 (mod 72)
, and for many other values of v.
