#set theory #groups
Consider the set H of all 3 × 3 matrices of the type: $\begin{bmatrix} a&f&e\\ 0&b&d\\ 0&0&c\\ \end{bmatrix}$ where a, b, c, d, e and f are real numbers and $abc ≠ 0$. Under the matrix multiplication operation, the set H is: (a) a group (b) a monoid but not a group (c) a semigroup but not a monoid (d) neither a group nor a semigroup

Determine whether the relation is reflexive, symmetric, and/or transitive?
Let R be the relation on the set ‘N’ of strictly positive integers, where strictly positive integers x and y satisfy x R y iff x^2 – y^2 = 2^k for some nonnegative integer k. Which of the following statement is true with respect to R? I think it’s just reflexive, because it obeys reflexive conditions.
