Data on spreads of nonsingular pairs


This data refers to spreads of nonsingular pairs (nsp-spreads, for short) in symplectic vector spaces (see Steven H. Weintraub, Spreads of nonsingular pairs in symplectic vector spaces, J. Geom. 86 (2006), 165-180).

There are the following files:

The spreads file for n=2, p=7 is approximately 2.25 gigabytes. Because of the length of this file, it has been broken up into 7 parts. Nevertheless, the total length of 2.25 gigabytes exceeds the capacity of this website, so these files are not available here, but can be obtained from the author upon request.
