Give you a statement and table with its title in Markdown format, please determine whether the statement is supported or refuted by, or is unrelated to the table. It'a binary classification problem, you should choose the answer between supported and refuted. Table cells in one row are seperated by '|', and different rows are seperated by '
'.

Table:
| model | floating point | decimal | byte string | memory map | max memory (kwords) |
| sigma 7 | optional | optional | standard | optional | 128 |
| sigma 5 | optional | n / a | n / a | n / a | 128 |
| sigma 6 | optional | standard | standard | standard | 128 |
| sigma 9 | standard | standard | standard | standard | 512 |
| sigma 8 | standard | n / a | n / a | n / a | 128 |
| sigma 9 model 2 | standard | standard | standard | standard | 256 |
| sigma 9 model 3 | standard | n / a | n / a | standard | 512 |
Title:
none
Statement:
standard is the value for the byte string when the memory map , decimal , and floating points are all standard and the max memory is smaller than 512
Answer:
supported
