Upon Amie Albrecht and Cathy Wilton's request, I am writing a blog post about a problem we worked on at One Hundred Factorial recently. A few weeks ago we became interested in problems involving removing spots from dice.

The titles of the two posts are:

• Spotless dice
• A Day of Maths 4: Spotless Dice
