Johnson Solid nr 1 to 17
Description
Once again I found a list of solids to design…. This time I hope I could design all of them in 3D. This time I’m not going to print them (there are 92 of them) but please place a picture with the number of solid I you do print one. I will publish them in several files with the title: Johnson Solid nr (the numbers in this post.) In 1966, Norman Johnson published a list which included all 92 solids, and gave them their names and numbers. He did not prove that there were only 92, but he did conjecture that there were no others. Victor Zalgaller in 1969 proved that Johnson's list was complete. Jn1: Square Pyramid Jn2: Pentagonal Pyramid Jn3: Triangular cupola Jn4: Square cupola Jn5: Pentagonal cupola Jn6: Pentagonal rotunda Jn7: Elongated triangular pyramid Jn8: Elongated square pyramid Jn9: Elongated pentagonal pyramid Jn10: Gryreolongated square pyramid Jn11: Gyreolongated pentagonal pyramid Jn12: triangular bipyramid Jn13: pentagonal bipyramid Jn14: Elongated triangular bipyramid Jn15: elongated square bypiramid Jn16: Elongated pentagonal bypiramid Jn17: Gyreolongated square bypiramid
