starn5t3b: Data: A 2-star of PG(4,2)

In IsoCheck: Isomorphism Check for Multi-Stage Factorial Designs with Randomization Restrictions

Description

A balanced 2-star of PG(4,2)

Usage

data(starn5t3b)

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 five subspaces f_1, f_2, f_3, f_4, f_5 given by f_1=(ABC,AC,CDE,B,BCDE,ABDE,ADE), f_2 = (AE,DE,AD,BCE,ABCDE,BCD,ABC), f_3 = (D,C,CD,ABCD,AB,ABD,ABC), f_4 = (E,ACDE,ACD,ABCE,BD,ABC,BDE) and f_5=(CE,A,ACE,ABC,BC,BE,ABE).

Note

In R, the data must be loaded using the data function.
