COMMENTS
| Lunnon defines "solution" to be the smallest value not obtainable by the best set of stamps. The solutions given in A001208 A001209 A001210 A001211 A001212 ... are one lower than this, that is, the sequence gives the largest number obtainable without a break using the best set of stamps. Here however "solution" is used in Lunnon's sense.
