Why do only bad things come in cubic liters? I saw a GreenPeace flyer celebrating the sabotage of a drainpipe dumping "thousands of cubic liters of pharmaceutical waste" into the ocean. Unfortunately, the photo showed only three-dimensional damage, leaving hundreds of square gallons unspilled, resulting in attacks by fifteen pound purple jellyfish:

Not at all. In R^6 they have even better machine shops than we do.

But there could be beautiful configurations for the Fano plane in higher dimensions. Maybe in 6-space, where the vertices of the unit simplex s_6 form 140 unit equilateral triangles. _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com https://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
