Are you ready? October is right around the corner and you know what that means? Mathober! This years prompts are on the website mathober.com and below.

If you are new to Mathober, no worries, you can jump right in. Each day there is a word or phrase for you to ponder, research, contemplate, and be creative with. You can share and find other's work by using #mathober or #mathober2026. Please note that there is only one "t" in Mathober.

You can use any medium, do as many or few prompts as you wish, and whenever you wish – in other words – no rules. Except, <dramatic pause> maybe a guideline that I added as a note in the about page:

This is a human endeavor, to dive in, to contemplate, to struggle, to create, and to grow.

I look forward to seeing the creativity, discussion, and play. Enjoy!

A list of days and prompts. In order: Perimeter of an Ellipse, Zebra Graph, Permutation List, Linear Recurrence, Inellipse, Connected Topology, Five Circles, Parabolic Rotation, K-Cyclic Graph, Simple Pole, Problem of Points, Reciprocal Prime Constant, Standard Map, Icositetragon, Irredundant, Isochronous Curve, Dimension Invariance, Biflecnodal Point, Orthic Triangle, Nice Vector Field, Prime Ring, Polylogarithm, Devil On Two Sticks, Multiperfect Number, Crossed Prism Graph, Unimodular Lattice, Indefinite Quadratic, Conic Double Point, Two Triangle Theorem, Spheroidal Wave Function, Existential Closure

This year I'd like to thank blinry for pairing on a fairly manual process to create the list and rolling the random numbers. From the random number, a word or phrase is pulled from a list in a spreadsheet. Some are thrown out and a number is re-rolled. The cut ones tend to be people's names, words with errors from an import issue, redundant from previous years, or overly simple. Sometimes, it might just be one word from a phrase to leave things open for interpretation.

I will post my creations in a separate post.
