Typically, grouping is used to apply some sort of aggregate function for each group. [1] [2] The result of a query using a GROUP BY statement contains one row for each group. This implies constraints on the columns that can appear in the associated SELECT clause. As a general rule, the SELECT clause may only contain columns with a unique value ...

For any two elements in the group, the table records what their composition is. Here we wrote "a 3 b" as a shorthand for a 3 ∘ b. In mathematics this group is known as the dihedral group of order 8, and is either denoted Dih 4, D 4 or D 8, depending on the convention.

Thus, both the first and second homotopy groups of a space are contained within its fundamental 2-group. As this 2-group also defines an action of π 1 (X,x) on π 2 (X,x) and an element of the cohomology group H 3 (π 1 (X,x), π 2 (X,x)), this is precisely the data needed to form the Postnikov tower of X if X is a pointed connected homotopy 2 ...
