Abstract
Numerous designs for triplet lenses, in addition to the well-known Cooke triplet and the inside-out triplet design, are possible. All are difficult to find on the computer because the starting point has to be very close to the final solution for the computer to find it. This paper describes a number of triplet solutions. All but the Cooke and inside-out triplet designs contain at least one thick element.
