Is the free abstract group residually of rank d > 2?
This rank was introduced by Malcev and is called special rank. Namely, The special rank of a group $G$ is the minimal $d$ such that every finitely generated subgroup of $G$ can be generated by $d$ elements. |

And why there are no such words $w(x,y)\in F_2$? |

Realizing a monoid as $\mathrm{End}(G)$ for some graph $G$
Actually, their theorem states this under some cardinality constraints: gdz.sub.uni-goettingen.de/… |

Powers of finite simple groups
The automorphism groups of finite simple groups are well known. So, we have to calculate the (non-reduced) Euler function $\phi_n(G)$ (ie. the number of generating n-tuples). In Section 1.1, Collins describes a technique of such calculations that allowed Hall (in 1936) to calculate, e.g., $\phi_2(A_5)=19\cdot 120$ (ie. $h_2(A_5)=19$). |
