Translation Generalized Quadrangles is essentially self-contained, as the reader is only expected to be familiar with some basic facts on finite generalized quadrangles. Proofs that are either too long or too technical are left out, or just sketched. The three standard works on generalized quadrangles are (co-)authored by the writers of this book: тАЬFinite Generalized QuadranglesтАЭ (1984) by S E Payne and J A Thas, тАЬGeneralized PolygonsтАЭ (1998) by H Van Maldeghem, and тАЬSymmetry in Finite Generalized QuadranglesтАЭ (2004) by K Thas.
