Two sets of sister chromatids .

No, chromosomes and chromatids are not the same. Chromosomes are long strands of DNA that contain genetic information, while chromatids are one of the two identical halves of a replicated chromosome held together by a centromere during cell division.
i think 26 i think 26 46 chromosomes. The sperm cell and egg cell each contain 23 chromosomes, totalling 46. The sperm cells and egg cells are known as haploid cells or sex cells (meaning having 1 set of chromosomes). Once the sperm cell and egg cell joins, a diploid cell is formed (meaning having 2 sets of chromosomes), and a zygote begins to form. The human body contains 2 sets of chromosomes, one maternal and one paternal.
A diploid cell contains two sets of chromosomes, one set inherited from each parent. This means that in humans, for example, a diploid cell typically contains 46 total chromosomes, with 23 chromosomes inherited from each parent.

sister chromatids (after DNA replication, but before dividing)
The term for the two sets of chromatids formed in the parent cell is "sister chromatids." During the S phase of the cell cycle, each chromosome is replicated, resulting in two identical copies that are connected at a region called the centromere. These sister chromatids are separated during cell division, ensuring that each daughter cell receives an identical set of chromosomes.

A chromosome pair, as in a pair of Chromosome 15, or a pair of Chromosome 5. Others have said Tetrad - Pls stand-by.
