Numbers mark filling factors of prominent FQHSs at ν = 4/5, 7/9, and 10/13 that belong to the 1-n/(4n + 1) sequence, with ν = 1, 2, and 3. In addition, there is a pronounced local Rxx minimum at ν = 13/17. The most interesting feature of the data is the FQHS at ν = 9/11 which does not belong to the 1-n/(4n + 1) sequence. The vertical arrow indicates the location of a Fermi sea of CFs at ν = 3/4.
