A system of domes as set forth in claim 1 wherein the set of end domes has domes with the length L equal to 4 1/2 feet and the set of intermediate domes consists of domes of two different lengths, whereby the first intermediate dome length is 9 feet and the second intermediate dome length is 13 1/2 feet.
8. A system of domes as set forth in claim 7 wherein the set of end domes comprises domes having lengths of 2 1/2 feet, 3 feet, 4 feet and 4 1/2 feet.
9. A system of domes as set forth in claim 7 wherein the set of end domes also comprises domes having a length of 3, 3 1/2 and 5 feet.
10. A system of domes as set forth in claim 7 wherein the set of end domes also comprises domes having a length of 4, 5 1/2 and 6 feet.
11. A system of domes as set forth in claim 7 wherein the set of end domes also comprises domes having a length of 5, 6 and 6 1/2 feet.
12. A system of domes as set forth in claim 2 wherein the set of end domes has domes with the length L equal to 3 feet and the set of intermediate domes consists of domes of three different lengths, whereby the first intermediate dome length is 9 feet, the second intermediate dome length is 12 feet and the third intermediate dome length is 15 feet.
13. A system of domes as set forth in claim 12 wherein the set of end domes comprises domes having a length of 2 feet.
14. A system of domes as set forth in claim 12 wherein the set of end domes comprises domes having a length of 4 feet.
