Assume we need to check if the 500g bagged milk produced by a certain company exceeds the standard level of melamine. We randomly sample 60 bags from a total of 800 bags of milk for inspection. To use a random number table to select the samples, we first number the 800 bags of milk from 000, 001, ..., to 799. If we start reading from the 7th row, 8th column of the random number table going right, the number of the fourth sample is ... (The random number table from the 7th line to the 9th line is excerpted below)

84 42 17 53 31  57 24 55 06 88  77 04 74 47 67  21 76 33 50 25   83 92 12 06 76
