This is where I keep data about all the small designs that I currently have on hand. This is very small at the moment, but will grow as I gradually construct or accumulate small designs. I would be glad to either store small designs constructed by other people or link to other sites.
The identification numbers that I will use are consistent with Mathon and Rosa's tables of designs in the CRC Handbook of Combinatorial Designs.
