... In the echelon method, you start with a matrix M and a unit matrix and, by simple arithmetic, change M into the unit matrix and the unit matrix into the inverse. Using r1, r2 , r3, c1, c2 , c3 to describe rows and columns, the technique is to start with the element in r1, c1 and make it 1 (by divisi ...

Solutions to Homework Set 6
... 1) A group is simple if it has no nontrivial proper normal subgroups. Let G be a simple group of order 168. How many elements of order 7 are there in G? Solution: Observe that 168 = 23 · 3 · 7. Every element of order 7 generates a cyclic group of order 7 so let us count the number of such subgroups: ...

Theorem: (Fisher`s Inequality, 1940) If a (v,b,r,k,λ) – BIBD exists with
... When testing a large number of samples for a rare attribute, it is efficient (faster and less expensive) to test large groups of these samples together for the attribute. It is desirable to then use the results of these pooled tests to deduce which of the samples had the attribute. Note that a negat ...
