Data: A 4-star of PG(7,2)
Description
A balanced 4-star of PG(7,2)
Usage
data(starn8t5a)Format
The star is formatted as a 3-dimensional array, where the [i,j,k]-th element indicates whether or not the ith basic factor is present in the jth effect of the kth flat of the star.
Details
The star consists of nine subspaces f_1, f_2, ,..., f_9 of size 31 each. Use vectortostring(starn8t5a) to see the elements of this star.
Note
In R, the data must be loaded using the data function.
