A mathematics enthusiast caring to help others out. When applicable, in the process of answering/helping out, I point people to the community effort http://www.proofwiki.org which catalogs and rigorously founds proofs in all areas of mathematics.
My most knowledgeable areas are logic and category theory. I also know a fair share about measure theory and functional analysis, along with the standard undergraduate curriculum.
For those trying to contact me urgently cq. personally, you can direct an email at the following address (all letters lowercase):

Find the smallest possible integer that satisfies both modular equations Thank you for responding; to make this information more visible, please edit it into the question body. As for the approach: It's a little sketchy, so I can't assess if you're really correct, but it can be turned into a viable strategy. An effective method can be distilled from this answer by Arturo Magidin. |

A question regarding the Power set This relates to the Axiom schema of specification (also: of comprehension), one of the usual axioms for set theory. |

Find the smallest possible integer that satisfies both modular equations Welcome to Mathematics.SE. I bring to your attention that Mathematics.SE is not a do-my-homework service. You should provide context, and show your attempts at the problem. A more detailed guide can be found here. Thanks in advance for your anticipated cooperation. |

Finite equivalence class same cardinality Done. I've put braces around \sim; you could also use \mathord\sim -- both make $\sim$ just a character to the interpreter. If you want spacing around the $/$ you can use \mathbin /: $X \mathbin/{\sim}$. |
